Abstract

An engine mount structure capable of efficiently absorbing vibration input from an engine is provided. The engine mount structure includes a front mount device 20 which is connected to an engine 1 and a subframe 10 to suppress vibration transmission from the engine 1 side to the subframe 10 side. A dynamic damper 26 connected to the subframe 10 to suppress vibration of the subframe 10 is disposed in a hole portion 11b, and an opening of the hole portion 11b is formed in an upper surface portion 11a of a front subframe member component 11 located on a lower side of the front mount device 20.

First claim

What is claimed is:

1. An engine mount structure, comprising a mount device, the mount device being connected to an engine and a subframe to suppress vibration transmission from the engine side to the subframe side, wherein
a dynamic damper connected to the subframe to suppress vibration of the subframe is disposed on a lower side of the mount device,
the subframe comprises a hole portion,
the mount device is connected to the subframe in a manner of being located on an upper side of the hole portion, and the dynamic damper is inserted to the hole portion, and
a connecting position between the subframe and the mount device is set in a position around the hole portion.

2. The engine mount structure according to claim 1 , wherein
the hole portion is disposed on an upper surface portion of the subframe,
the dynamic damper comprises a first installation member and a housing,
the first installation member is connected to the upper surface portion, and
the housing is inserted to the hole portion.

3. The engine mount structure according to claim 2 , wherein
the subframe comprises a lower surface portion in a position opposite the upper surface portion, and
the housing is spaced apart from the lower surface portion.

4. The engine mount structure according to claim 1 , wherein
the connecting position between the subframe and the mount device is set in a position farther away from the dynamic damper than a connecting position between the subframe and the dynamic damper.

5. The engine mount structure according to claim 1 , wherein
the subframe and the mount device are elastically connected via a rubber bush, and
the subframe and the dynamic damper are fastened rigidly.

6. The engine mount structure according to claim 1 , wherein elastic deformation directions of the mount device and the dynamic damper are identical in a vertical direction.
